Delhi’s peak summer power demand likely to hit 9,000 MW

Delhi’s peak power demand in the summer months, particularly during late June or early July 2025, is expected to hit 9,000 megawatts (MW) after reaching 8,000 MW for the first time in 2024.

According to sources in the State Load Dispatch Centre (SLDC), Delhi’s peak power demand is likely to hit 9,000 MW after scaling a record 8,656 MW in 2024. It had breached the 7000 MW mark for the first time (peaking at 7016 MW) in 2018.

The expected peak power demand during 2025 is an increase of more than 300 per cent over the peak power demand of 2,879 MW in 2002.

Delhi discoms—BSES Rajdhani Power (BRPL), BSES Yamuna Power (BYPL) and Tata Power Delhi Distribution (Tata Power-DDL)—have made preparations to meet the national capital territory’s rising electricity consumption.

BRPL and BYPL supply power to around 50 lakh consumers and roughly 2 crore residents in South, West, East and Central Delhi, whereas Tata Power DDL supplies electricity in North Delhi to around 20 lakh consumers and 90 lakh residents.

Peak power demand in BRPL’s area of South and West Delhi, which had clocked 3,809 MW during the last summer, is expected to reach around 4,050 MW in 2025.

On the other hand, in BYPL’s areas of East and Central Delhi, the peak power demand, which hit 1,882 MW during the summers in 2024, is expected to touch around 1,900 MW this year.

Last year, the power demand peaked at 2,481 MW in Tata Power-DDL’s area of operation during the summers and the discom expects demand to hit 2,562 MW in this season.

Tata Power DDL has made adequate power arrangements of up to 2,850 MW (apart from contingency planning) through long-term, medium-term and short-term tie-up arrangements.

BYPL and BRPL have made arrangements for over 2,100 MW of green power for the summer months. Besides, it has also made banking arrangements for 500 MW with states.

The green power includes around 888 MW solar power from SECI, 500 MW wind power, and 40 MW from Waste-to Energy. BSES efforts in ensuring reliable power are also being helped by over 160 MW of roof-top solar plants in South, West, East and Central Delhi.

Besides, BRPL will also procure up to 1,100 MW through bilateral contracts. In case of any unforeseeable contingency, BSES discoms will buy short-term power from the exchange, depending on the time-slot.

Tata Power-DDL is also fully geared to provide uninterrupted power supply by using advanced techniques and avenues like Bilateral Agreements, Reserve Shutdown and Power Exchange. Its Battery Energy Storage Systems (BESS) at Rohini and Rani Bagh will also support in providing continuous and reliable power to key customers during any emergency.

The Power Ministry expects peak electricity demand (Day) to hit 270 GW in FY26, which commences next month. India’s peak power consumption periods are from April to June and August to October.
